<div class="content">
partialUpdate(extraQuery)
</div>
<p class="heading2">Description</p>
<div class="content">
Sends a partial update request (AJAX request) to the server.<br><br>
This method will send the state of the JsChartViewer to the server using AJAX techniques. The web page will not be refreshed. It is expected the server will use a <a href="WebChartViewer.htm">WebChartViewer</a> to process the request, and return the updated state, the updated chart and/or the updated image map.<br><br>
During the partial update, a "rotating clock" icon (configurable using <a href="JsChartViewer.updatingMsg.htm">JsChartViewer.updatingMsg</a>) will appear on the chart to indicate that a partial update is in progress.<br><br>
This method is asynchronous. It will return before the update has been completed.
